Model: Lenovo Legion 5 2021 - r7 5600h + rtx 3070

I think I mess up the secure boot, I use Linux and try to setup Microsoft, big mistake, the laptop boot with hybrid graphics just fine. When I change the dGPU my laptop boot but showing a back screen, external display doesn’t work.

I know I can access in to the bios because if a enter the password wrong the pc beeps, in conclusion the dGPU is soft brick. I need to know the button combination to reset bios via the menu or the arrow keys combination to activate hybrid graphics.

I try to reset the bios by the power button method and by removing the battery and chmos but I think it doesn’t change the setting to the hybrid graphics or reset the secure boot keys.
